AP’s role in election night reporting depends on a basic fact about the United States: there is no single nationwide body that collects and releases results. The Associated Press says it fills that gap by compiling vote totals across jurisdictions and declaring winners in the period between Election Day and when official certification typically comes weeks later.
AP’s explainer describes the effort in three stages—collecting the vote, analyzing the developing tallies, and calling races. AP says it works to standardize data drawn from a patchwork of local counting systems that may not provide up-to-date tracking themselves, and it emphasizes quality control in converting those results into consistent terms and formats.
On the collection side, AP says it hires vote count reporters who work with local election officials to obtain results directly from counties or precincts where votes are first counted. The reporters submit results as soon as they are available, either by phone or electronically, and AP also gathers results from state or county websites when they are posted.
The AP says counties often update vote totals throughout the night as ballots are counted. According to the explainer, AP’s count is continually updated as those results are released, and in general elections AP says it can make as many as 21,000 vote updates per hour.
AP then moves to analysis. The explainer says AP looks at how many ballots remain uncounted and from which areas, and it also estimates turnout in races when official or exact tallies for outstanding votes are unavailable. AP says it uses those turnout estimates to track what share of the vote has been counted and what remains.
The analysis also includes attention to which ballots are still outstanding and how they were cast. AP says it tries to determine how counted ballots were cast and what vote types remain, including mail ballots and ballots cast in person on Election Day. AP links that breakdown to voting patterns it says can correlate with party preference, noting that voting by mail became highly politicized in the 2020 election.
AP says that in some states, election officials’ schedules or historical practice indicate which types of votes will be counted first, while in other states ballot types may be clearly marked when totals are released. The explainer offers an example: if a state begins by counting Election Day in-person votes and later counts mail ballots, AP says that may suggest an early Republican lead could narrow as mail ballots are tabulated; if mail ballots are counted first, AP says an early Republican lead could be a sign of a comfortable victory.
For race calls, AP says in almost all cases it can call outcomes before every ballot is counted, using its team of election journalists and analysts. The explainer says AP calls a race when a clear winner can be determined, but in competitive races AP may wait for additional votes to be tallied or for confirmation about how many ballots remain.
AP describes circumstances in which races may be “too early to call,” including states that continue counting large numbers of votes after election night. It also describes “too close to call” situations in which the race is so close that there is no clear winner even once all ballots except provisional and late-arriving absentee ballots are counted.
Overall, AP says its calls are not predictions and are not based on speculation. Instead, AP describes them as declarations grounded in analysis of vote results and other election data that one candidate has emerged as the winner—and that no other candidate can overtake that lead once all votes in the race are counted.
